It is one of the objectsof'this' vention to overcome this difficulty'byso peculiarly forn'iing. the operative parts o'the pe that `fi -tlieyand which'are so arranged'and formed thgit an accidental discharge ofthe inkvis practically impossible.:

is .so peculiarly formed that v,it can be turned in but onedire'ct-ion.andicannot be moved 'in- 'so that a is practically' impossible for thefingsrs grasping ythe `barrel to accidentally col '-pse the'tube anddischarge the ink. y

'07' Another object *ofthis inventionI is to provide. afilling mechanismwhich vis automatic i-nreleasing the flexibletube irrespective of theslow or quick turning of the ring.

l It has been found that the most desirable results obtained infillngcollapsible tubes of this nature isin releasing them suddenly andi permitting their sudden expansion'whereby the tubes areiuorecompletely 'filled than by Vallowing th'eni to expand slowly. Thering of this invention isv provided with novel means for suddenlyreleasingthe tubeafter the ring has completed a predetqjmined turningmovement, even if the ring is'fslowly turned.

Y i pletion ofthe `predetermined turning movement of :the ring, or whenthe tube is released.

The invention also embraces a novel means for insuring the expulsion ofthe air or other fluid from the tubewl1en the ring isturned.

Other objects and advantages of this invention will be more particularlypointed out in the following specification of the embo'diment of theinvention illustrated in the accompanying drawings.

In t e drawings: F'gure 1 is a side eleva` tion of the improvedself-filling fountain pen. Fig. 2 is a longitudinal section through thesame. Fig. 3 is a transverse section on the line 3-3 of Fig. 2. Fig. 4is a similar view showing the parts adjusted to collapse Athe flexibletube preparatory to filling the pen. Fig. 5 is a detail erspective viewof the presser bar employe Fig. 6 is a longitudinal section through thepen showing in normal .position the operative lparts andv a modifiedform of the presser bar. Fig. is .asimilar view-disclosing the `partsmoved into the position to `collapse the tube. Fig. 8 is a transversesection similar to Fig. 3 disclosing aslght modification in theoperating ring. Fig. 9 is a similar view dis` closing. a furthermodified form of the operating ring. Fig. 10 is a detail perspectiveview of the modified form of presser bar disclosed iii Figs. 6 and 7.

Referring to the drawings, in which simi- .lar characters of referenceindicate like parts throughout the several views, 13' designates thebarrel of the pen provided with the pen ,'section, pen point and cap inthe usual inannei. \V1thin the barrel 15 is located a flexiblctubc 16having suitable' connection with ink carried by the pen. lVithin thebarrel 15, and at-one side is located a longitudinal presser bar 1 7lying against the tube 16 throughout practically its entire length andhaving intermediate its endsl an outwardly extending pin 18. The barrell5 provided at one side with a small opening through which extends, andthrough which is adapted to slide, the pin 18 in moving the presser bar17 against and away from the colla psi ble tubelG.`

,The barrel 15 has .an annular depression its ends, through which thepin 1S projects at one'sidc of the barrel, the annular groove of thebarrel receiving a closely fitting ving or groove in-its outer surfaceintermediate the pen section and adapted to receive the 19 lyingsubstantially flat 'againslt the balrel. The ring 19, as may be bestseen from F'gs. 3 and 4, is provided at one side with an enlargementorprojectionO presenting opposed flat faces 91 for a )ui-pose hereinafterpointed out. lVitliin t ie enlargement 20, and at one side of the saine,is formed a groove 22 of a width sufficient vto receive the pin 18 andhaving an inclined .w'all eecentri'c to the axis of the ring 19 andserving asa Icani for operation avainstl lthe outer end of the pin 1S tomove the pin throughrthe side ofthe bai'rel 15 when the sleeve isrotated. The

projection .20 is provided at its opposite side -with an abrupt or sharpshoulder 23 adaptedrto suddenly release the pinx18'1after the same hasbeen compressed against the inner wall nf the sleeve 19 when the,sleevefis moved into normal position, as disclosed in Fig. 3. Normallythe pin 18 is extended and rests in the outer removed-end ofthe groove 1groove 2 2.

22, and .for the purpose of giving a visual indicationfof suchpositionof/the 'pin 18, the projection 20 is provided wi'tlra smallopening 244th'roiigh whichfinaybe' readily seen the outer end of the pin18, the'f'opening 24 registering with the outer end 'of' the In Figs.0,.'7 iid io niet@ is 'ai'sfitsed a slight modification in the yform of'"presser lbar. From Fig. 10 itwill be seen that-.the presser bar 17?. isenlarged at its innerend,`

and is given substantially wedge-shape'lso that the loiver surface o fthe presser 'liar 17 is incline.; toward the tube at its innerend. It isnotl necessary. that this'presserbar be of solid constructioiiasdisclosed: in the drawings, but it in ay be formed in any suitablen'iaiiner with an inclined face vfoifper forming the functions ascribedto thisparticular presser bar. \V heu the 'messer bar 17a is in no'rmal-position, as t presser bar. is removed slightlyfrom the tube.` Vlieiithe pi'csseiba r is ui'oved inwardly hy the ring 19 the upper end of thetube is first compressed and the fluid is expelled from that end priorto the compression of the lower end of the tube. Since the face is.iuclined the tube is compressed frouiilsuppcr to its lower endgradually, thus 'insuringr l'h e isclosed iii Fig G, the upper endthereof is in contact' with the tube 1G, while the lower end offihc.

The projection 20 is providediiwith op- )osed shoulders 23" n isadaptedjo move when the ring\"\`l9"' is turned to compress or releasethep1i`i`i\ `-The outer end or top .of the projection 20"`is pro` videdwith an indicator opening 24F through -adapted, to receive the outer endof the pin against vfhi'chtlie pin 18 which may be seen the upper end ofpin 18 when the same is extended, or in norefial position. "lien it. isdesired `to fill the pen, the bargrasped in the opposite hand. The flatsides :21,provide gripping surfaces 4for the'findrs in holdin" andturning the sleeve '19.*I-lie Sleeve 19 is rotated to'move the shoulderrelis grasped in one hand and the ring 19"= is away' `from the pin 18whereupon the cam'r wall of the groove 22 vis moved against the end ofthe pin 18 .and effects the gradual depression of the pin into thebarrel 15.3" As the pin l18 ismoved inwardly the presser bar '17 isforced against the flexible tube 16 and l(.ollapse'stlie same,'expellingthe air or other fluid from the tube. The pen sect-ion is nowTinsertedinto la quantity -of ink, and the sleeve19 `is'furthe'rrotatedin the -samedi'- rect-ion until the endof the pin 118 (passes-theshoulder 23'.-` The pin 18 is now su denly released from the shoulder 23and springs out^V wardlyunder .the pressure -of the tube 16into'the'outer end ofthe groove 22. This sudden releasing 'of the pin 18admits ofthe suddenexpansion of the'tube 16 whereupon the ink is Adrawnthrough the pensection and- .up into the flexible tube, nearly lfillingthe' same. v As soonas the pin 18 is released from `the shoulder 23-itisiiaps up into the outer end of thev groove 22 and mafv be seenthrough the indicator 'opening 21.'. lVlien the pin is tliusseeii atthis opening, t.he user under.- stands that tlie tube lil is expandedand that the pen lis filled. 3

lf desired, the indicatoi` opening 24 may be done away with, as isdisclosed in the structure of Fig. 8. The .snapping of the pin intonormal position when released fromthe shoulder 23 in this case is deemedsuflicient to give notice that the tube is expanded to its fullest.extent.

ln the modification shown in Fig. 9, the

projection 20" of the'ring A19 .is provided* with a pair of shoulders.23". both-of which are somewhat- 'graduah and which admitr ofvtheturning'of the sleeve 19" in either direction. 'ljVlien the pin 18is extended 011t- -wardly from the barreliin normal?position,v

such position may be readily ascertained by observingthe vpointofthe pin18 against or at the inner end of the opening 24".

The modification thleJ presser bar is disclosed in Figs. -6,7 audio,"the latter figurev showingin detail the structure ofthe resser-b'ar-17*L which has an inclined face W ereby oneend of the presserbabeomes into contact with the side of the tube before its`oppsite f1,060,137Y A, 4- g end, and wherein the tube'is Hat-tened gradul allyfrom its inner end to its outer end. The presser bar 17 is held with itsouter face in parallelism with the sideof the barrel 15 by the pin 18,the latter being guided in its movement .from wabbling or canting in thegroove 22. of the projection 20 which is car ried uponthe closelyfitting sleeve or ring 19. Vhen the pin 18 is moved inwardly from thegroove 22 the frictional contact between the inclined face of thepresser bar 17' and the side of the tube prevents the presser bar 17*from slipping'or cant-ing. It. is thus seen that during the entiremovement of the presser bar 17 its inner face is presented at4 all timesat an inclination to the axis of the tube 16, andthat the air in thetube is driven "from end to end in the tube as the latter is collapsed.As the presser bar 17 is moved inwardly by the turning of the sleeve 19the frictional contact between the presser bar 17 and the adjacent sideof t-he collapsible tube v16 increases. Since the presser bar 1'?"lcompresses the entire tube 16 against the opposite sideV of the barrel15 the adjacent side of the tube 16 is sti etched and exerts a slightdownward pull upon the presser bar 17, or

a pull in the direction of the open end of the barrel 15. This pull orpressure of the tube -16 tends to draw the upper enlarged endoftheress'er bar 17 toward the opposite side 'of t e barrell Vagainstthe tube 16. This actioninsures the collapsin et the upper Aend -of thetube 16 priorl to tiie collapsing of the lower en d of the tube evenwhen a presser barofuniform thickness, such as show n atv 1171 inI Figf,the 'enlargementl of the presser j. bar, as shown'al; 17 in Fig. 10,further invsuring the rior collapsing 'of the upper end i0 of the tube6.. Itis thus seen that when the' in 18 carried by the presser barismoved' inwardly from the slot and groove.\in 'the 'sleeve 19, the-frictional contact between the tube 16'and the` presser 'bar 17 or 17is suicient to hold the presser bar in its truc position. 'e Thiseculiar arrangement or form of 'the lface o the `presser 1bar providesfor means whereby the-tube is complete] exliausted of air or otherfluid, and wherein the fluid cannot be trapped in the .upper end of thetube. A l

The projection upon one side of the sleeve i 19 having-tile flat'sides21 serves as a rest or means for preventing the rolling of the j penbarrel when thehpen is placed upon a smooth surfacewhich is slightlyinclined. Thus the projection acts as a' stop to prevent the pen fromrolling'froni desks, tables or the like'which would result in the fallie(Ping of the pen and the probable injury.
